UNITED STATES PATENT OFFICE.

JACOB EDS'ON, OF BOSTON, MASSACHUSETTS.

TRUSS.

SPECIFICATION forming part-of Letters Patent No. 259,116, 'dated June 6, 1882.

Application led September 27, 1881. (Model.)

To all whom it may concern:

Be it known that I, JACOB EDSON, a citizen ci' the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Trnsses; and I do hereby declare that the same are fully described in the following specification and illustrated in the accompanying drawings.

This invention relates to improvements in trusses; and it is carried out as follows, reference being had tothe accompanying drawings, in whichl Figure l represents a front elevation of the invention. Fig. 2 represents a vertical section on the line A B, shown in Fig. l. Fig. 3 represents a horizontal section of the pad and strap. Fig. 4 represents a plan view of 'the under side of the pad 5 and Fig. 5 represents a plan view of the outside of the pad, as will hereinafter be more fully shown and described.

a is the pad, made of molded rubber or other elastic material, which is molded around the metal core G, the latter having liexible radial arms c c 0" 0"', adapted to be bent to any required shape, so as to tit the pad to the rupture for which it is to be worn. The rubber a, being molded around the metal core C, produces acorn posite pad, hard and firm in its central bearing and yielding at its outer periph ery-a very desirable object in a perfect truss.

v The under side ot' the pad ais made with a concave ledge, a', and the top is preferably made flat, as shown at b in Figs. 2 and 3, by

which the periphery of the pad is rendered very pliable and yielding.

c is a metal ball resting against the metallic core C, having a bearing thereon, and itis held in place by the upper elastic bearing, a'" a', so as to allow the balltc to be easily inserted into the pad and there held in place.

c is a screw-threaded shank, extending forward from the ball c, and madeA adjustable within the screw-threaded sleeve d, as shown in Fig. 3, to regulate the pressure on the body of the wearer,as may be desired. The base ot' the sleeve d is secured to the belt t and strap-clamp e by means of the screw g, as shown in Figs.2 and 3. The under side of the pad a is provided with suitable raised contigu'- rations, a4 a4, (shown in Fig. 4,) to prevent the pad from slipping or turning when in use. a5 is an aperture in the bottom of the pad a, and c is a similar aperture in the metal core C, which apertures serve for ventilation and passage of perspiration from the body oi' the wearer of the truss f is an arched abdominal guard, secured to the base of the sleeve d, which guard constitutes a bearing on the abdomen, to keep the pad in place and to receive a part of the pressure ofthe belt t', the center of the latter being arranged above that of the pressure on the pad, for the purpose ot reaching a lower rupture than could be reached with a pad having no such labdominal guard. v The guard f may be reversed or turned more or less to one side, or dispensed with altogether, if desired, to reach any required point of the body, or, if the rupture is sufticiently high, to enable the belt to do the work without such guard.

his the lever-fastener, having pear-shaped opening h', adapted to be locked on the head g of the screw g. The lever-fastener h has 'three cross-bars, h" h3 h4, for the purpose of holding and regulating the length of strap t', as shown in Figs. 1 and 3. The perforated end h of the lever-fastener h constitutes a lever to give the required pressure on the body without undue tightness of the strap. A tripod bearing on the body of the wearer is obtained by the arched abdominal guard j', com bined 4with the pad a and end h4 of the leverfastener lt, by which arrangement the truss can be worn with perfect ease and with less discomfort as compared with other pads and trusses now in use.

Having thus fully described my invention, I wish to secure by Letters Patent, and claiml. The combination of the elastic pad, having a central socket and an opening leading through the ilat side of the pad to its said socket, with the screw-threaded pin provided upon one end with a ball received into the socket in the pad, the screw-threaded sleeve formed with a base-plate and adapted to receive the-screw-threaded pin, and the clampplate secured by a screw to the base-plate of the screw-threaded sleeve, substantially as described.

2. `The combination, in a truss, of the pad IOO 4. The elastic pad provided with internal metallic arms, serving in its center as a bearing for the ball C of the connecting-rod e2, and having the. annular elastic holding a for connecting the pad to the ball and to admit of its easy removal, substantially as shown and dcscribed.

In testimony whereof I have affixed my sig nature in presence of two witnesses.

JACOB EDSON.
